STAPLE.

SPECIFICATION forming part of Letters Patent No. 312A60, dated February 17, 18 65.

Application filed October 20, 1584. (No model.)

To all whom it may concern:

Be it known that I, JONATHAN Haren'r, of Pittsfield, in the county of Berkshire and State of Massachusetts, have invented a new lmprovement in Staples; and I do hereby declare the following, when taken in connection with accompanying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents a perspective view of my invention.

This invention relates to an improvement in staples designed with special reference to securing the lines of wire to the posts in wire fence, but applicable to securing lines of wire for other purposes, the object of the invention being a construction of staple which will securely hold the wire to the post, and whereby each post may take its portion of the strain upon the line of wire; and the invention consists in a bent or U-shaped staple having the inside of the bend serrated, and'as more fully hereinafter described.

In' the manufacture of the staple I prefer to make it from square wire bent into U shape, one leg, A, longer than the other, B; but the length of the legs may be the same, or varied to a greater or less extent. Upon the inside of the bend the surface is serrated, as at a, and

so that the sharp serrations, when the staple is driven, will come in direct contact with the surface of the wire, and thereby increase the frictional bearing between the surface of the staple and the surface of the wire, and so as to prevent the wire slipping through the staple.

The serrations may be formed in the surface of the wire before bending or after, the method of forming such serrations constituting no part of the present invention.

In bending the staple care should be exercised that the inner or serrated surface correspond substantially to the circumference of the wire: and so that the serrations may take a firm bearing on the wire.

I claim- As an article of manufacture, the herein-described U-shaped staple having the inner surface of the bend serrated, substantially as described.

JONATHAN HAIGHT.
